Oh and the specs are bone stock, just k&n air filters. Now I'm looking for the catted down pipes and a tune. I'm leaning twards Dinan's. the warranty is a big thing for me. Don't want to void the warranty on something I spent 98k on.

I'm curious about hooking up an actual boost gauge. My Torque app says I'm getting 17.4psi pre and post tune, but my tuner MorePower (morepower.de) says I should be getting beyond 20psi now. It feels faster, but the boost pressure hasn't changed, just the AFR from before and after at WOT.

hey on that torque app make sure you are using actual boost not whats commanded, if you have a piggy back tune the boost that the dme is commanding doesn't change. Also the gauges you should be using are boost,afr, & rpm. Those are the ones to keep on and then the rest on your back up screens.

I didn't see options to change the boost from commanded vs actual, just the AFR, which you can see I have those two gauges up. Is it something I change in the settings on the app itself?

I was reading a thread on the N54 forums where a guy had used a 7" tablet, a custom made bracket and the BMS JB4 app - http://www.n54tech.com/forums/showthread.php?t=34123 Seeing that their dashes are different and the JB4 can't be used on an E series vehicle, I'll be creating something myself here soon using the same tablet but just using Torque and the simple $5 eBay OBDII dongle I've been using for years.

Played with some settings and made an actual "vacuum/boost" gauge but depending on the settings it'll only read 2.9psi on two of them and the highest I got was 15.9 on the other, all while the manifold pressure gauge is still pegging at 17.4psi.

The only actual vs commanded is AFR. I'm not in the car now, but these don't change regardless. I did post a screenshot of being able to change the MAF reading in settings, but vacuum/boost still only going to 15.9psi at most while intake manifold pressure is only going to 17.4psi.
